It’s 1986 and there’s trouble in Macarthur Park, and Mabel Hackenbush, better known as Dr. Hackenbush of Dr. Hackenbush and her Orchestra, is up to her neck in it. She’s trying to help out her friends Anna Kodaly and Ross, and winds up in the middle of a mystery in the elderly Westlake section of Los Angeles. Oh, and during all this she and the band and are playing gigs wherever and whenever. It’s a Hackenbush mystery in the best tradition of the other Hackenbush mystery, “Dr. Hackenbush Gets Some Culture.”
